Herzog & de Meuron and Piet Oudolf explore the meaning of a garden with Calder Gardens

Philadelphia has gained a new cultural landmark. Calder Gardens joins a network of institutions that includes the Barnes Foundation, Rodin Museum, and Franklin Institute within walking distance of the city’s main cultural corridor, Benjamin Franklin Parkway. For the project, Herzog & de Meuron transformed the site with an 18,000-square-foot pavilion and landscaping, which was helmed by Piet Oudolf who planted over 250 varieties of plants across the 1.8-acre expanse as “more of a tribute than a museum,” he told AN. The nexus of the $90 million endeavor is a rotating display of Alexander Calder’s work featuring sculpture, drawings, and paintings set within largely subterranean galleries.
